Title: Method and device for image reading
Inventor: HAYASHI TOSHIO
IPC: H04N1/19
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent the unevenness of read image density that is caused by dust, etc., attached on a 2nd density reference plate by discontinuing the operation of an original illumination means which corrects the variance of light quantity with the 2nd density reference plate, if the drive of a reading position moving means is stopped during a read operation of an original image. SOLUTION: When an image read operation is discontinued, a CPU 1202 receives a read discontinuation instruction from an external device and makes every control part discontinue the image reading operation. At the same time, the CPU 1202 sets a signal 'swoff' at 0, to turn off the analog switches 1206 and 1207 and sets the input of a time constant circuit 1203 in a floating state. Thus, it is possible to prevent the uneven density of a read image that is caused by the dust etc., and to improve the quality of images read by a scanner, by fixing the voltage level that is inputted to a terminal Vt of an A/D converter 1201, even if dust, etc., are attached on the 2nd density reference plate when an image reading operation is discontinued.

IPC: H01L27/04
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device whose malfunction is hardly generated when an undershoot is superposed on an input signal. SOLUTION: A node N1 to which an input signal is given is connected to the drain of an N-channel transistor 74a whose gate and source are coupled to a ground potential. The source part of the N-channel transistor 74a is formed on the sidewall of a trench part 86. Consequently, since an open angle α at which electrons are injected into a P-type silicon substrate 120 from the node N1 is restricted by an n<+> region 88 as the source part of the N-channel transistor 74a, the amount of the electrons which are injected can be reduced.
